How much does the bar weigh?

Sorry for the newb question but im new to lifting and want to know how much the bar that you put the weights on weighs. There are different ones to like the one for bench presses and one for thats smaller and has big curves for like bicep curls. Also how much would my bench be if I can lift one 45 pounder on each side which makes 2, would my bench be 90 pounds or do you include the bar? thank you.

I've always wondere what are ez-bar? 25-35lbs I've heard. How much do those little oly bars weight like 35lbs?

IDK if anyone else ever seen these bars, but in high school are weight room had a lot of them. They were a 7' oly bar, but a little thicker, and deeper knurling. They were black instead of chrome like all the fancy POS bars. Everyone said they weighed 55lbs. Some said 50lbs. I don't know what they weighed, but I do know a little more they had to they were like and 1/8'' thicker. I liked a thick bar I could grip it better, and it wouldn't bend. I don't know who made these bars but everyone said they were meant for squating, deads, and powercleans.

My gyms got the thicker black bars too, I wonder if they are 50-55lbs. I don't think though cuz they're Invako (nice quality)

I bought an olympic EZ bar two weeks ago and I asked the same question. It just so happened that there was a scale on the floor (a "bathroom" type). So, I first weighed myself and then weighed myself again holding the bar.

I did the math and that one came to exactly 17 pounds. I don't know if there is an "official" weight for EZ-Curl bars. In my workout calculations, however, I call it 15 pounds because it makes the math easier.

Yes actually. I weighted myself. Then I weighted myself and the tape (wrapped around my waist). Then I wrapped the tape around the ez bar. Then I weighted everything together. And then I called my grade school sister to help me with the math. But it came out to 15lbs, give or take a few ounces.
